  • Publication number: 20050024414
    Abstract: Described are systems and methods for printing that use an optical sensor that is moveable relative to a print medium, and a mark that is visible to the optical sensor within the range of movement of the optical sensor. The mark provides a fixed and known location that can be used to establish a position of the optical sensor relative to the print medium.

  • Publication number: 20050021001
    Abstract: A catheter for use in delivery or withdrawal of a formulation, wherein the catheter has an outer layer comprising a bio-compatible material and a barrier layer comprising a material that provides a more effective barrier than the outer layer against inward and outward diffusion of substances that may cause destabilization of the formulation. The outer surface of the barrier layer contacts at least a portion of the inner surface of the outer layer. The catheter may include a flared distal end tip to aid in the release, during a bolus delivery or catheter flush, of any obstruction situated at the distal end tip of the catheter. The larger cross-sectional area at the flared distal end tip minimizes the chances that any obstruction that develops at the distal end tip will be sufficient to hinder the flow of the formulation within the lumen of the catheter.

  • Patent number: 6816091
    Abstract: An interpolation circuit and method for interpolating first and second out-of-phase ramp signals are disclosed. The interpolation circuit generates fractional ramp signals from the ramp signals and utilizes four multiplexers and two comparators to compare selected ones of the ramp signals. The comparator outputs are used by a finite state machine to provide a next state for the interpolator from the current state and the comparator outputs. The signals selected by the multiplexers are determined by the current state generated by the finite state machine. The finite state machine also detects a startup condition and determines the correct current state from the comparator outputs when different ramp signals are applied to the comparators. The ramp signals can be generated from out-of-phase signals from an optical comparator. The interpolation circuit generates new out-of-phase signals having a larger number of states per cycle.

  • Publication number: 20040193090
    Abstract: A communication device (CD) exchanges messages with an implantable infusion pump via telemetry such that commands are supplied thereto and operational information is obtained therefrom. The CD is controlled, at least in part, by a processor IC according to a software program operating therein and provides feedback to a user via a visual display, an audio alarm, and a vibrational alarm, and allows input from the user via a touch sensitive keypad. Certain input functions are restricted by password. The visual display includes an icon and fixed element display region and a bitmap display region. The fixed element display region includes time and date displays, battery and drug level displays that decrement, and a moving delivery state display. Various screens allow operational or log information to be displayed and/or user entry of commands. Program features when disabled are removed from a series of screen options that can be scrolled through.

  • Patent number: 6076328
    Abstract: Connection apparatus for connecting frame members and panel members is provided for constructing a storage building primarily from sheet metal. The apparatus utilizes connecting members that may be made from thermoplastic or metal materials. The number of threaded fasteners and time required to assemble the storage building is reduced dramatically from that of prior designs.
